== Required Packages ==
 * bison
 * flex
 * git (git-core)
 * gperf
 * libncurses development headers (libncurses-dev)
 * make (build-essential)
 * mksquashfs (squashfs-tools)
 * openjdk
 * pngcrush - the build process will complain if it is not installed but builds will complete.
 * wget (or curl)
 * zip
 * zlib development headers (zlib1g-dev)

=== Additional requirements for amd64 ===

 * libc6-dev-i386
 * gcc-multilib
 * g++-multilib 
 * lib32z1-dev 
 * lib32readline5-dev
 * lib32ncurses5-dev
 * 32-bit compatibility libraries
 * If you see errors about incompatible library versions, you may need some symlinks. For example:
   * sudo ln -s /usr/lib32/libstdc++.so.6.0.14 /usr/lib32/libstdc++.so
   * sudo ln -s /usr/lib32/libz.so.1.2.3.4 /usr/lib32/libz.so

== Warning ==
 Do not build as root, always build as user.
== Setup ==
Get and install the repo tool
{{{
 mkdir bin
 cd bin
 wget http://android.git.kernel.org/repo
 chmod a+x repo
 cd ..
}}}
Get replicant 2.2
{{{
 mkdir replicant-2.2
 cd replicant-2.2
 ../bin/repo init -u git://gitorious.org/replicant/manifest.git -b replicant-2.2
 ../bin/repo sync
}}}

== Each time you want to build replicant 2.2 ==
{{{
cd ~/replicant-2.2
 ../bin/repo sync
source build/envsetup.sh
export ANDROID_JAVA_HOME=$JAVA_HOME
lunch replicant_dream_sapphire-eng 
make -j$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) bacon  #uses arguments like -j9 to speed up build in case of multi-core cpu
}}}
Don't forget the bacon at the end, without that you will have some build errors.
Note that the bacon also produces standard images like system.img, just ship or use the system.img like images

You will find your built images in ./out/target/product/dream_sapphire/.

You will also find fastboot, needed to install the images, in ./out/host/linux-x86/bin/.

Now you are ready to [http://trac.osuosl.org/trac/replicant/wiki/Installation install!]
